The line between concern (GUYS WEATHER RADAR IS SHOWING END TIMES) and curiosity (check out this neat radar image I saw) can be pretty thin in technical spaces.
Creative minds in the community are very good at filling in the blanks, no matter the accuracy.
(a) early in their radar-watching journey, and starting to notice the finer details in radar products, or;
(b) looking to stir unfounded panic by exaggerating a pattern that’s filtered out or not noticed by others, in light of current events.
Unlike the NEXRAD images in question, the noise floor on the Internet this is quite high and hard to differentiate between the two.
